1 Claim. (Ci. 33-23) This invention relates to an adaptor for scribersof the type employed in reproducing letters or characters fromtemplates, and has as its primary object the provision of an adaptor bymeans of which a pencil, pen, or other Writing implement of conventionaldesign may he employed with such scribers without the necessity ofproviding a special attachment shaft thereon.

A further object of the invention is the provision of an attachment ofthis nature which may be readily applied to any conventional scriber,particularly those of the type which normally grip a round shaft of aconventional printing tip or pen, which will readily accommodate anyconventional pencil, ballpoint pen, fountain pen, or other standard orwriting implement, and which may be applied to the scriber with aminimum of time, effort, and difficulty.

A further object of the invention is the provision of a device of thischaracter which will securely retain the associated writing implement ina position whereby characters may be readily reproduced from templates.

A further object of the invention is the pr vision of device of thischaracter which enhances the speed and accuracy of reproduction ofcharacters from the template due to the fact that smearing ink may beavoided, the point of the pencil or pen is more clearly visible to thoperator, and small letters or numerals may be produced readily andexpeditiously.

Still another object of the invention is the provision of such a devicewhich is sturdy and durable in construction, reliable and eificient inoperation, and relatively simple and inexpensive to manufacture,assemble, and utilize.

Other objects will in part be obvious and in part he pointed out as thedescription of the invention proceeds, and shown in the accompanyingdrawings wherein:

FIGURE 1 is a top plan view of one form of conventional scriber andassociated template showing the adaptor of the instant inventionassociated therewith.

FIGURE 2 is an enlarged top plan view of the portion of the scriber ofFIGURE 1 showing the conventional method of securing the shaft of aprinting tip therein.

FIGURE 3 is a side elevational view of the scriber and template ofFIGURE 1 together with the adaptor of the instant invention.

FIGURE 4 is a longitudinal sectional view taken vertically through theattachment of the instant invention and the tip of the scriber as shownin FIGURE 1.

FIGURE 5 is a fragmentary view showing a modified form of adaptor; and

FIGURE 6 is a top plan view of an alternative form of scriber with anadaptor bushing therefor which enables the adaptor of the instantinvention to 'be used.

Similar reference characters refer to similar parts throughout theseveral views of the drawing.

Having reference now to the drawing in detail, there is generallyindicated at 10 a conventional scriber which includes an elongated body11 having at its rear end a tail pin 12 and an upper guide knob 13. Thetail pin 12 travels along the longitudinal groove 14 of a conventionaltemplate 15 having letters or other indicia 16 cut therein.

The body has mounted thereon an adjustable arm 17 which carries a tracerpin 18, which follows the lettering or indicia 16 as the tracer is movedfor reproducing the indicia. A clamp arm 19 is also provided having anadjusting screw 2%, beyond which is a clamping jaw 21 at the extremityof a longitudinal split 22, the clamping jaw being controlled by aclamping screw 23. The usual arm lock 24 and handrest 25 complete theassembly.

In the usual employment of the device the round portion 26 of the shaft'of a standard printing tip or pen is clam-pingly engaged between thejaws 21 and held by means of the clamping screw 23.

The adaptor of the instant invention is generally indicated at St andincludes a shaft 31 of a diameter substantially equal to that of theconventional shaft 26 previously described. At its upper end shaft 31has fixedly secured thereto a collar 32 to which is connected an annulusor ring 33 of relatively large diameter, or of a diameter sufficient tosurround the shaft of a. conventional ballpoint pen or pencil 34. A setscrew 35 extends through a threaded bore in the-side wall of annulus 33and is provided with a head 36 by means of which the pen or pencil 34may be tightly clamped in position for reproducing the characters orindicia 16.

By virtue of this arrangement any conventional pen, pencil, or otherwriting implement of relatively large diameter may be readily employedin conjunction with a conventional scriber, without the necessity ofemploying a standard printing tip or pen, and the resultant use ofspecialized ink. Also, by virtue of this arrangement the cleaning andcare of fine instruments such as drawing pens employing the usualrounded shaft may be completely eliminated.

FIGURE 5 discloses a slightly modified form of construction wherein ashaft 40 has fmed thereto a collar 41, from which a sheet 42 extends toan annulus 43. In this case the interior of the annulus 43 is providedwith a downwardly tapered bore 44 of slightly lesser diameter than thatof a conventional pen or pencil 45, the arrangement being such that thetapered tip 46 0f the implement seats within the downwardly taperedbore, and is held in position thereby. The operation is identical tothat of the previously described modification.

FIGURE 6 discloses a modified form of conventional scriber generallyindicated at so which includes a body 51, a tail pin 52, an adjustingarm 53 having a tracer pin 54- at the end thereof, a clamp arm 55 and aheight adjustment screw 56, jaws 57 governed by a clamp screw 58 beingprovided at the end of the arm 55. This is a standard scriber, and issubstantially identical in operation and use to that of the previouslydescribed modification except that the jaws 57 are larger fortheaccommodation of different types of shaft of drawing tips. In orderto adapt this device to use with the adaptor of the instant invention abushing generally indicated at 60 is provided which includes a cup 61having an outside diameter suitable for seating between the jaws 5'7,and an internal bore 62 of a diameter to accommodate the shaft 31 or 40.An annular flange 63 surrounds the upper portion of the cup 61, andseats on top of the jaws 57. The use and operation of the device of thisform of the invention is substantially identical to that previouslydescribed.

From the foregoing it will now be seen that there is herein provided animproved adapt-or for scribers which will permit the use of anyconventional writing or drawing 9 a implement therewith, and whichaccomplishes all the objects of this invention, and others, includingmany advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as manymodifications may be made in the embodiment hereinbefore shown anddescribed, it is to be understood that all matter herein is to beinterpreted merely as illustrative, and not in a limiting sense.

I claim:

An adaptor for a scriber of the type including a clamping device forholding the round shaft of a conventional printing tip, said adaptorincluding a shaft of a diameter corresponding to a conventional printingtip, adapted to be engaged in said clamping device and extend upwardlytherefrom, a collar having a periphery fixed to the upper end of saidshaft, a ring having a periphery and defining an opening substantiallylarger than the round shaft of a 4 conventional printing tip, meanstangentially connecting the periphery of said collar and the peripheryof said ring whereby said ring extends in horizontally offset relationto said collar, and means associated with said ring for securing anelongated, substantially cylindrical, portion of a standard writinginstrument therein.
